I mean, this is the case for a lot of things? Has always been the case.
If you host friends over for dinner at your house a lot, nobody will ever say you are subject to the same rules as a restaurant. You start letting other people host dinners at your house, and things could change. You start letting people solicit your place for paid dinners, similar outcome. Do it once, nobody will probably know or care. Continue to do it at scale, though, and I don't know why you would expect to not be subject to regulations.
The problem is obviously that the government shouldn't be regulating private speech. They pass these rules by saying "look how big Facebook is, they need to be regulated" when the actual problem is that they need to be decentralized. But then the rules don't apply only to Facebook, and worse, are designed under the assumption of a centralized service so that they entrench the thing that should be eliminated.
